Bora Bora
Enclosed lagoon, no strong-current constraint, shallow sites. The manta rays at Anau are inside the lagoon. It is the most beginner-accessible diving destination in French Polynesia.

Diving Bora Bora or Rangiroa?
These are not two versions of the same dive. Bora Bora is a sheltered lagoon where you can do your first dive. Rangiroa is two passes swept by tidal current, with grey reef sharks by the dozen and a resident community of 25 to 30 bottlenose dolphins. The right choice depends on your actual experience, not your ambitions.
In one line
Bora Bora if you dive sometimes. Rangiroa if that is why you came.
Rangiroa
The Avatoru and Tiputa passes are drift dives. Centres open most sites to "any certified diver", but explicitly require experience of current in the passes and solid buoyancy control for Le Bleu and Les Failles.
What about Fakarava?
If sharks are the point, that is where to go. A 2016 study in Current Biology measured a mean of 600 reef sharks in the south pass, with a per-hectare biomass two to three times any other documented shark aggregation on Earth.
What cannot be promised
No animal encounter, no visibility, no dive. Only the local centre can say what is diveable on the day, given tide, swell and group.
The table
What actually separates them
| Bora Bora | Rangiroa | |
|---|---|---|
| Island type | High island, enclosed 78 km² lagoon | Atoll — 2nd largest in the world, 80 km lagoon |
| Access from Papeete | 50-min flight + 15-min boat | 1-hour flight, 356 km |
| Air Tahiti return | from 40 246 XPF | from 37 718 XPF |
| Passes | One: Te Ava Nui | Two: Avatoru and Tiputa |
| What you see | Manta rays (Anau), lemon sharks (Tapu), leopard rays (Toopua) | Grey reef sharks by the dozen, resident bottlenose dolphins, hammerheads in season |
| Level required | No published minimum; sheltered lagoon, suits beginners | Sites open to any certified diver, but current experience required in the passes |
| The real limiting factor | Visibility at Anau, cut by plankton | Tidal current — dives are planned around slack water |
| Who it suits | First dive, occasional diver, lagoon holiday | Autonomous diver who came to dive |
Rangiroa
The passes, the current, and the dolphins of Tiputa
Rangiroa is the largest atoll in French Polynesia and the second largest in the world: a lagoon 80 km long and 5 to 32 km wide, with two passes in the north. Everything is organised around them.
A community of 25 to 30 bottlenose dolphins (Tursiops truncatus) lives year-round in the Tiputa pass area. They are not spinner dolphins, contrary to what is often written: the species is confirmed by the NGO Dauphins de Rangiroa, which has monitored the population for over fifteen years. These animals have been habituated to divers for decades and some individuals interact intrusively — one more reason to follow the briefing.
The hammerheads at Tiputa are great hammerheads (Sphyrna mokarran), seen from December to March; 29 to 30 distinct individuals were identified between 2019 and 2021 by the Mokarran Protection Society. It is one of the few sites in the world where the species is observed without baiting.
| Site (Rangiroa) | Depth | Level | What you see |
|---|---|---|---|
| Motu Nuhi-Nuhi, “the Aquarium” | Shallow | Beginners, training | Reef fish, coral |
| Avatoru reef | 15–20 m | Any certified diver | Whitetip reef sharks, bigeye trevally |
| Petite Passe (drift) | max 20 m | Certified with current experience | Blacktip sharks, manta rays, groupers, morays |
| Tiputa reef | from 15 m | Any certified diver | Hawksbill turtles, grey sharks, napoleon wrasse, rays, dolphins |
| La Marche (drift) | 25–49 m | Experienced | A “carpet” of grey reef sharks, hammerheads in season, rays |
| Le Bleu | 100 m below you | Strong buoyancy control | Barracuda, tuna, grey and silky sharks, dolphins |
| Les Failles (outer reef) | 10–49 m, 1 h 30 boat ride | Strong buoyancy control | Groupers, trevally, tuna, grey and whitetip sharks |
One local centre requires a refresher dive after more than a year out of the water. That is good practice rather than a formality: in a pass with real current, approximate buoyancy is a genuine problem.
Bora Bora
One lagoon, one pass, and mantas
Tahiti Tourisme lists eight certified centres on the island and three main sites: Anau (manta rays, in a protected zone), Tapu (an underwater pass where large lemon sharks live) and Muri Muri (a drift over white sand, with schools of trevally).
Rarely mentioned: Anau is inside the lagoon and its visibility is reduced, the water being loaded with plankton — which is exactly what draws the mantas, and exactly what disappoints photographers expecting brochure turquoise. Toopua drops to 30 m on a sandbank, a feeding zone for leopard rays. Muri Muri, on the ocean side, drops to 35 m over sand inhabited by garden eels. Te Ava Nui, the island's only pass, is dived as a drift and comes back up along a wall of blue coral specific to Bora Bora.
No Bora Bora centre publishes a minimum level per site. Tahiti Tourisme says only that instructors adapt dives to each diver.
Conditions
Water, visibility, seasons
Water stays between 26 and 29 °C all year — 26 °C in August and September, 29 °C from February to April. A light wetsuit is enough at any time. Visibility, as stated by Tahiti Tourisme, often reaches 40 metres, with the documented exception of Anau.
The dry season runs June to September, the warm wet season November to April. Two windows worth knowing: hammerheads at Rangiroa from December to March, and the Fakarava south wall of sharks, densest in June and July — the scientific reference points to the full moon, whose exact month shifts from year to year.
Humpback whales: the rules changed on 1 December 2024
Legal observation season 20 July to 20 November, 07:30 to 17:30. Minimum distance: 100 m for licensed professional boats, 300 m for private boats, 15 m for swimmers. Maximum three boats in the observation zone, one per company group, six people in the water per vessel. Ninety-two licences country-wide, with drone enforcement. French Polynesia has been a marine mammal sanctuary since 2002.
Common questions
Diving in French Polynesia: FAQ
Do I need an advanced certification to dive Rangiroa?
Not formally. Centres open most sites to any certified diver, but specify “with experience of current” for pass dives and “strong buoyancy control” for Le Bleu and Les Failles. One centre requires a refresher dive after more than a year out of the water. Recent experience matters more than the card.
Can I do my first dive at Bora Bora?
Yes. The lagoon is sheltered, the main sites are shallow and there is no strong-current constraint. No centre publishes a minimum level per site; instructors adapt the dive to the group.
When can I see hammerheads at Rangiroa?
December to March, in the Tiputa pass. The species is the great hammerhead, Sphyrna mokarran; between 2019 and 2021, 29 to 30 distinct individuals were identified there. No sighting can be guaranteed.
Rangiroa or Fakarava for sharks?
Fakarava, if that is the only criterion. A 2016 study in Current Biology measured a mean of 600 reef sharks in the Tumakohua south pass, with a per-hectare biomass two to three times any other documented aggregation. The south pass is accessible from level 1 and age 12; the Garuae north pass, at 1 600 m the widest in French Polynesia, requires intermediate to advanced experience.
What does a dive cost?
As a published reference from an identified Fakarava centre on 19 August 2026: 10 500 XPF for an exploration dive, 14 900 XPF for a first or refresher dive, and a 14 000 XPF supplement for the south pass day trip. Rates vary by island and centre.
Safety
What this page does not replace
The local centre decides, not this page
Current, swell, tide, which site is actually open and who is in the group change every day. No certification exempts you from the instructor's assessment, and no animal encounter is guaranteed. Check that your insurance covers diving and medical evacuation: in French Polynesia an evacuation is a flight, not an ambulance.
